Cause. Nearly every case of trichinæ, which has been brought to the notice of the profession, has been attributed to the eating of raw or improperly cooked pork. The parasites can only be detected with a microscope.
Treatment. The impossibility of removing the trichinæ after they have passed into the muscles is apparent; and, as yet, no special remedy has been recommended to remove them from the alimentary canal. The only safety lies in prevention. Hence raw or imperfectly cooked pork should never be eaten.
DYSPEPSIA.
It is generally conceded that a multitude of human ailments arise from indigestion, and in its various forms it taxes the skill of the physician to prescribe the proper remedies. It is undeniable that the closest intimacy exists between happiness and good digestion. A healthy digestion aids materially in making a cheerful disposition, and the "feast of reason and flow of soul" is due as much to the functional integrity of the stomach as to a strong and generous mental organization. Dr. Johnson severely said: "Every man is a rascal as soon as he is sick." We all know that a morbid condition irritates the individual and excites sarcastic and disagreeable remarks. And, likewise, an irritable temper and, suddenly aroused passions may not only turn and disturb the stomach, but even poison the secretions. Anxiety, excitability, fear, and irritability frequently cause the perversion of physiological processes.
The slightest functional disturbance of the stomach deranges, more or less, all the succeeding operations of digestion and tends to the vitiation and impairment of the delicate processes of nutrition. Dyspepsia may commence and proceed so insidiously as not to excite the suspicion of friends, although the patient generally desires active treatment, such as cathartics, emetics, and medicines to act upon the liver. When the disease becomes confirmed, it presents some of the following symptoms: Weight, uneasiness, and fullness in the region of the stomach, attended by impatience, irritability, sluggishness, anxiety, and melancholy; there is impairment of the appetite and taste, also sourness, flatulency, and, perhaps, frequent attacks of colic, loss of hope, courage, and energy; apathy, drowsiness, and frightful dreams are also symptoms common in the different stages of this disease. There are, furthermore, the accompanying symptoms of a coated tongue, bitter taste in the mouth, unpleasant eructations, scalding of the throat from regurgitation, offensive breath, sick headache, giddiness, disturbed sleep, sallow countenance, heart-burn, morbid craving after food, constant anxiety and apprehension, fancied impotency, and fickleness. The subjects of dyspepsia frequently imagine that they require medicines to act upon the liver, desire active treatment, are endlessly experimenting in diet, daily rehearse their symptoms, and are morbidly sensitive.
Causes. Overtasking the body or mind, overloading the stomach, the use of improper food, such as stale vegetables and meat, unripe fruits, indigestible articles, improperly prepared food, irregular meals, disorderly habits, the use of alcoholic stimulants, loss of sleep, masturbation irritability of temper, anxiety, or grief may all give rise to indigestion. If the functions performed by the skin are embarrassed by cold, tight clothing, or lack of cleanliness, the nutritive changes cannot properly take place throughout the body, and consequently the digestive functions are embarrassed, as the revolutions of a water-wheel are impeded by the backset of the water. When food is not thoroughly masticated, it is not properly mixed with saliva of the glands of the mouth, and is not prepared for digestion by the acids of the stomach.
Whatever diminishes the general strength, impairs the health, or encroaches upon the functions of life, also hinders the perfect solution of food and disturbs in a measure the function of digestion. Whatever diminishes the normal amount of the digestive secretions or perverts their quality, deteriorating their solvent properties, is a cause of dyspepsia. This should be borne in mind in selecting remedies.
Treatment. The hygienic treatment consists in the regulation of the daily habits, proper selection and preparation of the food, cultivation of cheerfulness, diversion of the mind, and cleanliness of person. We cannot give particular directions as to the kind of diet, as there are no established rules for guidance. Generally, a dyspeptic knows best, from experience, what articles of diet can be taken with the least injury. The directions applicable to the condition of one patient, are not suited to those of another. In dyspepsia, animal food is, as a rule, preferable. Foods rich in starchy matter often ferment and produce distress. Sometimes alkalies may be given with beneficial effect, when there seems to be an excess of acid in the gastric secretions.
